Drop Reason
(cont’d)
Pre-AnsDrop The call disconnected before answer by an endpoint.
The cause of the disconnect may be the network, an endpoint, or a
terminal adapter. This drop reason is different from ‘No-answer,’ which
indicates that a 60-second timeout occurred while alerting. In this case,
the call drops before the 60-second timer has expired. Some busy
endpoints connected through terminal adapters display this behavior.
Resource MCU could not provide resources (VC or MMI) when the call
arrived or lost the resources during the call. This could be due to them
being Out of Service, busied out by craft, or being used by system
maintenance. This drop reason could also occur if the DS1/MMI cable is
disconnected. If there was a resource problem when the call arrived, it
would get reorder (fast busy) and not get disconnected by the MCU.
Password Either the user entered the wrong password or the audio
add-on user did not enter it within the specified time period. Note that
the audio add-on user gets one attempt to enter a correct password and
inter-digit timing for each digit (that is, about 10 seconds between
digits).
System An MCU restart (level 2) disconnected all calls.
UIN-Inv The user entered an invalid User Identification Number.
Unknown The system could not determine the cause of the disconnect.
Wrong-num This dial-out drop reason occurs when the MCU detects
the wrong destination number was dialed. This drop reason is detected
by MCU CPTR resources SDN cause value. See “Dial-out” for details.
UCC controller intentionally disconnected the endpoint.
AC Num Administered Connection Number - from 1 to 128. AC number can be
used to further diagnose a problem by combining status conference
information with the status administered connection command and
data stored in the error and alarm logs.
Ports Trunk The data endpoint that the channel is using.
Ports Video The MMI port for the channel.
Ports Aud If the endpoint type is not “UCC,” the VC audio encoder port (which is
always paired to a decoder port) for the channel (only the first channel).
Because only one audio encoder port is allocated per endpoint, it
appears together with the ESM data port in the endpoint’s channel 1
port slot position of the Port Aud/ESM column. For “UCC” endpoint
type, the channel 1 port slot position displays the allocated Call
Classifier resource.
Ports ESM The Expansion Service Module MMI data port. This field is always blank.
Sum Grp Endpoint’s assigned summer group number. The summer group port
assignments are on screen 1.
